ALSA: hda - Add "Mute-LED Mode" enum control
Create snd_hda_add_vmaster_hook() and snd_hda_sync_vmaster_hook() helper functions to handle the mute-LED in vmaster hook more commonly. In the former function, a new enum control "Mute-LED Mode" is added. This provides user to choose whether the mute-LED should be turned on/off explicitly or to follow the master-mute status. Reviewed-by: David Henningsson <david.henningsson@canonical.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
